Isimangaliso Sendawo: I-Howranite Yakha Isakhiwo Sayo Esingapheli
Ngaphansi kobuso boMhlaba, ukuguquka kokuhamba kancane bekulokhu kwenzeka izigidi zeminyaka. I-Granite, idwala eliyi-igneous elakhiwe ngokupholisa kancane nokuqina kwe-magma, lithola ukuzinza kwalo okumangalisayo ngenxa yesakhiwo esiyingqayizivele sekristalu esakhiwe phakathi nale nqubo yokwakheka ende. Ngokungafani namadwala e-sedimentary, ahlukaniswe futhi athambekele ekuqhekekeni, noma amadwala e-metamorphic, angase abe nezindawo ezibuthakathaka ezivela ekuphindaphindweni kwe-crystallization okubangelwa ukucindezela, i-granite yakha ngaphansi komhlaba lapho i-magma iphola khona kancane kancane, okuvumela amakristalu amakhulu amaminerali ukuba akhule futhi ahlangane ngokuqinile.
Le matrix ekristalu ehlanganayo ngokuyinhloko iqukethe amaminerali amathathu: i-quartz (20-40%), i-feldspar (40-60%), kanye ne-mica (5-10%). I-Quartz, enye yamaminerali avame kakhulu anobulukhuni be-Mohs obungu-7, inikeza ukumelana okumangalisayo kokuklwebheka. I-Feldspar, enobulukhuni bayo obuphansi kodwa inala kakhulu, isebenza njenge-"backbone" yedwala, kuyilapho i-mica yengeza ukuguquguquka ngaphandle kokwehlisa amandla. Ndawonye, la maminerali akha izinto ezihlanganisiwe ezimelana kokubili namandla okucindezelwa kanye nokucindezeleka kangcono kakhulu kunezinye izindlela eziningi ezenziwe ngabantu.
